百度多文件异步上传控件webuploader基本用法解析

<div id="uploader"></div>
<asp:HiddenField ID="hfFilePath" ClientIDMode="Static" runat="server" />

MVC版后端文件接收，即便你是asp.net 引入mvc做ajax也是可以的：

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.Mvc;
public class WebUploaderController : BaseController
 {
  public ActionResult Process(string id, string name, string type, string lastModifiedDate, int size, HttpPostedFileBase file)
  {
   string filePathName = string.Empty;string localPath = Path.Combine(HttpRuntime.AppDomainAppPath, "UploadDocument");
   if (Request.Files.Count == 0)
   {
    return Json(new { jsonrpc = 2.0, error = new { code = 102, message = "保存失败" }, id = "id" });
   }
   try
   {
    filePathName = //自己在这里处理文件保存并返回需要保存到hidden的数据，文件在file或者Request.Files[0]   }
   catch (Exception)
   {
    return Json(new { jsonrpc = 2.0, error = new { code = 103, message = "保存失败" }, id = "id" });
   }
   return Json(new
   {
    jsonrpc = "2.0",
    id = "id",
    filePath = urlPath + "/" + filePathName
   });
  }
　　　　 static string urlPath = "../../Upload/Document";
  public ActionResult Delete(string filePathName)
  {
   if (string.IsNullOrEmpty(filePathName))
   {
    return Content("no");
   }
   //为了安全 检查一下路径 不够严谨 自行更具业务做更加细致的判断
   if (!filePathName.StartsWith(urlPath) ||
    filePathName.Substring(6, filePathName.Length - 7).Contains("../"))
   {
    return Content("no!");
   }
   string localFilePathName = this.Server.MapPath(filePathName);
   try
   {
    bool b = UploadifyManager.DeleteAttachment(localFilePathName);
    if (!b) throw new Exception("删除文件失败");
    return Content("ok");
   }
   catch
   {
    return Content("no");
   }
  }
 }

补充：

扩展自定义参数，利用uploadBeforeSend事件可以扩展参数，插件内可根据需要修改。

cookie的问题，我用微软自带的登录系统，不需要做任何特殊处理完全没有问题。
